Yocto on the Edge - Unusual challenges when building not so embedded systems
- Anna-Lena Marx

- Embedded , Conferences
Building embedded systems with Yocto on ARM platforms is a common practice, but when the products move further to the edge and become less “embedded,” new challenges arise. In this session, we will explore the requirements and challenges faced when developing Yocto-based systems for edge computing based on Intel.
We will dive into topics such as provisioning x86-based platforms, securely managing Linux user logins on a read-only root file system with enforced password changes, and implementing A/B updates together with secure boot. Real-world project requirements will be used as a guide to discuss practical solutions and best practices for addressing these challenges.

Advanced System Profiling, Tracing and Trace Analysis with Perfetto in Android and Yocto

Together with my colleague Stefan Lengfeld.
Tracing is a capable mechanism for deep system analysis and profiling with a minimal overhead. By recording defined system events, in Linux but also Android, tracing can be used to analyze concurrency or latency issues, for example. Android’s systrace tool made it easy to analyze and correlate traces and events due to a graphical UI, in order to help developers identify performance bottlenecks. The successor to this advanced and convenient tool is called Perfetto. It’s available for pure Linux too, and part of Yocto (meta-oe) since Langdale now. In the talk, we’ll have a look into
